aix下的catopen求助
小弟现在在aix下作开发，将原来HP-UX下的工程移植到AIX下，目前遇到一个问题
使用catopen函数去打开一个.cat文件时老是出错（在原HP-UX下没有这个问题），NLSPATH设置是正确的/home/guard/lib/nls/msg/C/%N，文件的名称也是正确的，文件的读写权限也是正确的，但是调用catopen就是会出错(返回值为-1)，但此时我把errno是打印出来为0，errno表明没有出错，很是奇怪，请大家帮帮忙
有没有可能是因为HP-UX下与AIX下.msg文件的格式不同，在AIX使用原.msgt生成的.cat文件无法使用，我的.msg文件格式如下

没有用过catopen，只能给你贴一段说明。
希望对你有用[code]Return Values
The catopen subroutine returns a catalog descriptor. If the LC_MESSAGES category is set to the default value C, and the LC__FASTMSG environment variable is set to true, the catopen subroutine returns a value of -1.
If the LC_MESSAGES category is not set to the default value C but the catopen subroutine returns a value of -1, an error has occurred during creation of the structure of the nl_catd data type or the catalog name referred to by the CatalogName parameter does not exist.[/code]
此说明是aix 4.3的
hp的说明和aix不同。hp B.11如下
[code]
RETURN VALUE
Upon success, catopen() returns a message catalog descriptor.
Otherwise, catopen() returns a value of (nl_catd)-1 and sets errno to
indicate the error.
Upon success, catclose() returns zero. Otherwise, catclose() returns
-1 and sets errno to indicate the error.[/code]
好像aix不会设置errno，而hp会？ 是这样么？

终于发现问题在哪里了，只要我在catopen里使用全路径名，就可以正确打开.cat文件，难道catopen不是使用NLSPATH环境变量么？我的NLSPATH环境变量肯定是设置正确的，如下
/home/guard/lib/nls/msg/C/%N
我使用的全路径名是/home/guard/lib/nls/msg/C/commonmsg.cat
而且我使用dspcat命令来显示commonmsg.cat的内容时，也必须使用全路径
难道catopen，dspcat不是使用NLSPATH来搜索.cat文件么？或者还有什么别的设置，使得catopen，dspcat没有使用NLSPATH？
期待高手解释一下
ps:感谢楼上的帮助
ivhb
还是aix的一段说明：
[code]
If the catalog file name referred to by the CatalogName parameter contains a leading / (slash), it is assumed to be an absolute path name. If the catalog file name is not an absolute path name, the user environment determines which directory paths to search. The NLSPATH environment variable defines the directory search path. When this variable is used, the setlocale subroutine must be called before the catopen subroutine.
[/code]
不知道对你是不是有用
ivhb
好像是要加
setlocale(LC_ALL, "C");
anonyaniu
dspcat使用了NLSPATH。
还要搜索系统目录/usr/lib/nls/msg/en_US的cat文件。确认一下是否有重名。
